|When it comes to ruby and sapphire, there is no place more famous than Myanmar’s Mogok Stone Tract.|
The Mogok Stone Tract is in Myanmar’s Mandalay province, about 200 km northeast of Mandalay. Home to the world’s premier ruby mines, it is also one of the richest mineral concentrations on Earth. Aside from ruby, Mogok produces many gems, including sapphire, spinel, peridot, topaz and moonstone. One of Mogok’s gems, painite, is found nowhere else on the planet.
During certain periods in the Earth’s history, tectonic activity produced large-scale deformation of the surface. This stress resulted in fantastic zones of mineral formation, where mundane minerals mutated.
Mogok and other villages nearby have been famous since ancient times for its gemstones, especially ruby and sapphire.
|Mogok is a city in the Mandalay Region of Burma (Myanmar), located 200 km north of Mandalay. |
90% of the world's rubies come from Myanmar. The red stones from there are prized for their purity and hue. The "Valley of Rubies" is noted for its rare pigeon's blood rubies and blue sapphires.
|In 1886, the British succeeded in taking over Upper Burma. By 1889, they had formed Burma Ruby Mines Ltd. They introduced water cannons, washing plants, and other mechanized mining methods. The company promoted Burmese rubies in Europe and around the world.
Operational problems and falling prices due to the introduction of synthetic ruby caused the company to abandon the mines in 1931.
|The military junta was dissolved following a 2010 general election.||Burma became an independent nation in 1948. Following a coup in 1962, a military dictatorship took over until 2011.|
Burma's ethnic groups have been involved in one of the world's longest-running unresolved civil wars.
Although the military retains influence through the constitution that was ratified in 2008, it has relinquished control of the government.
|The geological environment features impressive marble pinnacles (karsts) that are blackened from weathering. |
The formations are visible throughout the stone tract. One of the largest of these outcroppings is the one that the temple Kyauk Pyat sits upon.
|The karsts result from the weathering of the marble. This weathering process also plays a part in mining at Mogok. Marble is an intricate component of ruby and spinel formation.|
The host rock is weathered and transported along with the gems. The gems are then concentrated in gravels.
|In March 2012, a draft foreign investment law emerged, the first in twenty five years. Foreigners will no longer require a local partner to start a business in the country, and will be able to legally lease, but not own property. |
In 2012, the Asian Development Bank formally began to finance infrastructure and development projects in the country. The United States, Japan and the European Union countries have also begun to reduce economic sanctions to allow foreign direct investment.
